Little is known about how insecure attachment affects aggressive behavior and well‐being among Vietnamese youth. Using structural equation modeling, we investigate the mediating role of subjective social status (SSS) on the paths from insecure attachment to overt aggressive behavior (OAB) and psychological well‐being (PW) in a sample of 1753 Vietnamese adolescents (Mage = 16.136, SD = 0.784) and test whether the results will be replicated in another sample of 601 Vietnamese young adults (Mage = 19.93, SD = 1.35). Participants complete a survey comprising demographic information, attachment styles, SSS, OAB, and PW questionnaires. Our main findings include: (a) anxious attachment positively related to OAB in both samples, (b) anxious attachment was only negatively associated with adolescents' PW, (c) avoidant attachment was positively correlated to OAB in adolescents but negatively correlated in young adults, and (d) avoidant attachment was negatively related to PW in both samples. In addition, (e) in adolescents, the mediation role of SSS was significant in all paths, but (f) SSS only mediated the link from avoidant attachment to PW of young adults. The present study suggests that aggressive behavior might not be associated with social status or attachment in the same way in adolescents compared to young adult Vietnamese samples.

A core–shell Fe3O4@C nanocomposite consisting of a layer of amorphous carbon functionalized on the Fe3O4 surface has been synthesized via a simple hydrothermal process of a suspension of Fe3O4 nanoparticles and glucose. Using this approach, the thickness of the amorphous carbon shell can be well controlled by changing the mass ratio of Fe3O4 nanoparticles to glucose. The specific characteristics of Fe3O4@C were also analyzed. The results obtained revealed that the adsorption of methylene blue (MB) onto the Fe3O4@C nanosorbent is strongly dependent on the thickness of the carbon shell. The Fe3O4@C nanosorbent could be recovered for reuse with 83% effective removal at the 5th cycle. With its excellent performance, Fe3O4@C nanocomposite has great potential applications as a smart nanosorbent, including high adsorption capacity, recoverability and recyclability for organic dye removal.
